Past simple vs. Present perfect

Hiểu bài

The textbook contrasts completed past events with experiences or changes connected to the present. Exercises include “He (see) _____ the doctor yesterday,” “She (suffer) _____ from a serious headache, but after treatment, she felt better,” “Our living conditions (improve) _____ over the last few decades,” and “The doctor (just, examine) _____ her.” The page also gives the recent-time example “We have just moved to Hai Phong.” Learners choose a tense by considering whether a finished past time is stated or whether the action has present relevance. Blanks remain unanswered for independent practice.
